> especially relevant in Japan, where the country’s adult population eats more than double the World Health Organization’s recommended intake

Japan is also the country with the second highest life expectancy in the world. Is salt really that bad? How long would they live if they followed WHO's recommendations?

No it isn't unless you are salt sensitive. You would know if you are salt sensitive, you would have high blood pressure.

I'd take some years off my life if it meant I could continue to enjoy salt.

Iirc only the northern parts of Japan have high salt diets, the south side has lesser intake, but I could be wrong.

I don't think this is true at all, everyone here eats a lot of salt.

Soy sauce is in basically everything, it's full of salt.

I was wondering, does exercise purge "extra" salt?

also, since this is japan, would they have a chopsticks model? Maybe this is for soup. Or an export version. Japanese ramen spoons have a different shape.

When I first heard about that Kirin invention I heard about chopsticks also, so maybe it is in the works

Not really. Of course you tend to drink and sweat more, which contributes.

IIRC sweating is the only way for the body to get rid of salt, so on paper, yes. But it's probably not as simple as that.

No. Absolutely no. The kidneys take care of it pretty good.

No. Your kidneys do this, assuming they work correctly.

Is salt consumption and life span uniformly distributed across Japan?
Re:Kirin demos "electric salt spoon" at CES by bamboozled on Saturday January 11, 2025 @05:35AM (#42664885)
Everyone in Japan eats a lot of salt, there is no region specific salt intake.

No, salt is good because it helps you to eat unpalatable, nutritious food.

And Na is absolutely vital, and depending on your diet, if you cut 100% of table salt you will get deprived of Na and Iodine

It's not just one thing. Their diet very low calorie.. Low on fat.

If we eat oil like Mediterranean fat like Intuit's, carb like Raramurii, protein like Americans will have worst health of all.

Re:Kirin demos "electric salt spoon" at CES by Blackthorn on Saturday January 11, 2025 @10:45AM (#42666595)
Source for the low calorie bit? Seems unlikely, given the amount of rice consumed.
Re:Kirin demos "electric salt spoon" at CES by smolder on Sunday January 12, 2025 @07:58AM (#42673246)
You seem to be assuming "the amount of rice consumed" is high, but are you taking into consideration that the average portion may be small?
Re:Kirin demos "electric salt spoon" at CES by wenc on Saturday January 11, 2025 @12:27PM (#42667361)
Dietary fat isn't actually bad for you in reasonable amounts. It's the overindulgence of carbs, which turns into body fat.

Also the Japanese diet is interesting. It's actually not low-calorie pound-per-pound, but the portion sizes are much smaller. The Japanese just eat less than Americans.

It has also a surprisingly small amount of greens. There is usually a pickled vegetable dish on the side, but that's it.

Re:Kirin demos "electric salt spoon" at CES by f1shy on Saturday January 11, 2025 @06:27AM (#42665151)
Actually a healthy person can regulate Na levels very good. There is a lot of debate if it is as bad as portrayed.

Im very tempted to think the japanese have higher life expectancy because they are on average much shorter than western europeans with similar quality of life.
Re:Kirin demos "electric salt spoon" at CES by rafaelmn on Saturday January 11, 2025 @10:50AM (#42666634)
You can check this by comparing Japanese who lived in different countries. I vaguely remember it doesn't hold up, but should be simple to search.

Here's a brief video that makes the claim that you probably need more salt in your diet. He has 3 more salt videos, if you're intrigued.

This guy is not a healthcare professional and makes intentionally contrarian videos for views. He is cherry picking information and ignoring decades of science on nutritional sodium. Please listen to your doctor, not some random YouTuber trying to monetize your attention.

As aren't you (and i). And why should i listen to a random Hacker dude? Or a smoking doctor? Dou you think every GP is a nutritionist? And even then...

Re:Kirin demos "electric salt spoon" at CES by wenc on Saturday January 11, 2025 @12:36PM (#42667429)
I watch this guy a lot. I noticed a few things.

He does two things that increase believability: he cites papers and studies, and he runs experiments on himself. This is good.

He does one thing that decreases believability: he only cites papers and studies that reinforces his contrarian points, and benignly ignores the rest. This is called being a YouTube influencer.

In ML terms, his content has high precision and low recall -- he optimizes for true positives but not false negatives. It's a form of confirmation bias. You can still use his data (which I assume to be correctly sourced), but you might want to be skeptical of his conclusions by seeking your own disconfirming evidence.

Show us, then. He cites his sources. The least you can do is do the same.

tl;dr: Higher (yes, higher) sodium intake correlated with longer life expectancy and lower mortality but the study was observational and not a basis for dietary recommendations.

Meanwhile the garbage science that got us "salt = blood pressure" has made it into dietary recommendations just fine, ruining food all over the world.

Salt is not bad for you. The small hypertension decreases people experience on low sodium diets are capped at roughly 10% and salt is almost never the actual cause. It is another victim of choosing a boogie man to hide the fact that sugar is by far the most destructive thing to consume by a huge margin
